IMPRovED DUMPlNc--CART Specification forming' part of Letters Patent No. 441.068, dated September 6, 1864.

To all whom 'it may concern:

Be 1t known that I, THEoDoRE BLoDGETT, ofjBelchertown, in the county of Hampshire and State of Massachusetts, haveinvented a new and useful or Improved Self Loading and Discharging Cart; and I do hereby declare the same to be ful-ly described in the following;v

specification and represented in the accompanying drawings, of whichi Figure 1 is a top view, Fig. 2 aside elevation, and Fig. 3 a longitudinal section, of it.

In Fig. 2 one of the wheelsis Shown-asbnoken supported by two chains,'E E, each of which is fastened to the periphery'of one of two eccentrics, F F, alixed 6u a cross-shaft, G. The journals ofthe said shaft G are supported in boxes ll H, upheld by the thills, and there is fixed on the shaft a ratchet, a. A lever, b, carrying an impelling-pawl, c, turns on shaft G as a fulcrum, and is arranged by the side of the ratchet, and so that the impelling-pawl may act with the teeth of such ratchet. A retaining-pawl, d, is also used with the ratchet, and serves, when in engagement with the ratchet, to holditfrom revolving. The bottom of the scoop is open or has a discharging-open ing made through it, such' openingbeing provided with a flap erdoor, e, which is hinged to thescoop, and when closed is held in place by a turn-button, j', which is operated or turned by manual force applied toa hand-lever, j, ar-

ranged as shown in the drawings. A drivers seat, h, is placed over the axle and thills and supportedby two springs, i d, extended from a cross-bar, k, disposed as seen in Figs. 1, 2,`

and 3. The object' of the eccentrics FF is to enable a greater leverage to bebrought into action to raise thescoop at the commencement of elevating it ont o f the ground than may be necessary to effect-its further' elevation.

In the operation of this cart the scoop is to be dropped so as to rest with its front end on the ground'to be excavated. As the cart may be drawn over the ground `the scoop will plunge into and below the surface thereof, and, 'passin g nnderneathzit, will be eausedtotakc up more or less of the earth. Aftera sufficient quantity of earth may have accumulated in the scoop the attendantby applying his hand lo the hand-lever of the im pelling-pawl, is to vwork such hand-lever back and forth, soas io 'produce a rotary movement of the eecentrlcs anda consequent elevation of the scoop. ln order to discharge the contents of the scoop, the turn-button is to be rotated so as to allow the door or Hap to fall, in which case the earth will drop out of the scoop. Subsequently the scoop-door may be raised up by force applied to a chain, K, applied toit and suspended from the drivers seat.

l. The combination and arrangement ot' the eccentrics'F F with the shalt G, the scoop D, its lifting-chains E E, and the operative mechanism of such shaft.

2. The anraugement ofthe scoop D on the axle ot' the supporting-wheels, in combination with the arrangement ot' the scoop-elevating machinery on thills, as specified.

v 3. The combination of the hinged doo'reand' its' holding mechanismj'g with the scoop D,it's

elevating mechanism, and the wheels and thills or their equivalent forconnectiug one or more draft-animals to the cart.
